Peb cov khoom siv feem ntau thiab lawv cov yam ntxwv hauv kev tsim pwm

Raws li cov cuab yeej tseem ceeb hauv kev tsim khoom, pwm tau siv dav hauv ntau qhov chaw, xws li kev tsim tsheb, khoom siv hauv tsev, kev ua cov yas, thiab lwm yam. Hauv pwm tsim, kev xaiv cov ntaub ntawv tseem ceeb heev vim tias cov khoom sib txawv muaj cov yam ntxwv sib txawv thiab siv tau. Hauv tsab xov xwm no, peb yuav tham txog peb cov khoom siv feem ntau hauv kev tsim pwm: cov khoom siv hlau, cov ntaub ntawv yas, thiab cov khoom sib xyaw, thiab tshawb xyuas lawv cov yam ntxwv thiab kev siv.
1. Cov khoom siv hlau
Cov khoom siv hlau yog ib qho ntawm cov khoom siv feem ntau siv hauv kev tsim pwm. Cov khoom siv hlau feem ntau suav nrog cov cuab yeej hlau, stainless hlau, thiab txhuas alloys. Cov ntaub ntawv no muaj lub zog siab, hardness, thiab hnav tsis kam, ua rau lawv tsim nyog rau kev tsim pwm ruaj khov. Cov cuab yeej hlau yog cov khoom siv pwm feem ntau, uas tau muab faib ua ob hom: cov cuab yeej ua haujlwm txias thiab cov cuab yeej ua haujlwm kub. Cov cuab yeej ua haujlwm txias yog tsim rau kev tsim cov pwm me me, xws li stamping thiab txiav pwm, thaum kub ua haujlwm cov cuab yeej hlau yog tsim rau kev tsim pwm loj, xws li pwm tuag-casting thiab yas txhaj pwm.
Stainless hlau kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim pwm, vim nws muaj kev tiv thaiv corrosion zoo thiab kub oxidation tsis kam. Qhov no tau ua stainless hlau pwm dav siv hauv teb xws li kev ua zaub mov thiab kev tsim khoom siv kho mob. Tsis tas li ntawd, aluminium alloys feem ntau yog siv los tsim cov pwm pwm, tshwj xeeb tshaj yog thaum yuav tsum tau prototyping sai, aluminium alloy pwm tuaj yeem txhim kho kev tsim khoom.
2. Cov ntaub ntawv yas
Cov pwm yas ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom yas. Cov pwm yas feem ntau yog ua los ntawm cov yas yas siv zog ntxiv nrog cov iav fibers, xws li polyamides (nylon), polycarbonates, thiab polystyrene. Cov ntaub ntawv no muaj kev hnav zoo thiab cov tshuaj tiv thaiv corrosion, thiab tsim nyog rau kev tsim pwm rau cov khoom yas, xws li cov khoom yas, lub raj mis, thiab lwm yam.
Nylon pwm yog siv dav hauv kev lag luam xws li cov khoom siv tsheb thiab cov khoom siv hauv tsev vim lawv lub zog siab, hnav tsis kam, thiab roj tsis kam. Polycarbonate pwm muaj cov tshuaj tiv thaiv zoo heev thiab tsim nyog rau kev tsim pwm uas yuav tsum tau muaj kev tiv thaiv corrosion, xws li cov thawv ntim tshuaj. Polystyrene pwm feem ntau yog siv rau cov khoom siv yas, xws li cov khoom siv hauv tsev thiab cov khoom ua si.
3. Cov khoom siv sib xyaw
Nrog rau kev tsim cov thev naus laus zis, cov ntaub ntawv sib xyaw tau maj mam siv rau hauv kev tsim pwm. Cov ntaub ntawv sib xyaw yog tsim los ntawm ob lossis ntau cov ntaub ntawv sib txawv ua ke los ua kom muaj txiaj ntsig zoo ntawm ntau yam ntaub ntawv. Piv txwv li, carbon fiber reinforced composite cov ntaub ntawv muaj lub zog siab, tsis tshua muaj yuag, thiab zoo heev corrosion kuj, ua rau lawv haum rau manufacturing high-kev ua tau zoo pwm, xws li cov nyob rau hauv aerospace kev lag luam.
